What is the maximum transmission distance of a Category 5 network cable Category 5 network cable and

1. The internal structure is different. The internal structure of the six types of network cables adds a cross skeleton, and the four pairs of cables of the twisted pair are placed in the four grooves of the cross skeleton, and the cross skeleton of the cable ** rotates with the change of length. There is no cross skeleton inside the Category 5 network cable.

2. The size of the copper core is different. The copper core of the five types of network cables is below, and the standard of the six types of network cables is different for the external labeling. The outer skin of the five types of network cables will be marked with the word "cat5"; The outer skin of the six types of network cables will be marked with the word "cat6".

4. The scope of application is different. Category 5 network cables are mainly used for 100 Gigabit networks and 10 Gigabit networks, and have been replaced by Super Category 5 cables. Category 6 network cables are mainly used in gigabit networks, and their transmission performance is much higher than that of Category 5e network cable standards.

According to the regulations on cabling in the standard ANSI TIA EIA, the maximum transmission distance is 100 meters, regardless of the type of network cable, and the transmission distance exceeding the standard affects the speed and the quality is the same thing, and the quality depends on the speed.

The theoretical value is 100 meters, but how many can pass 50m without attenuation in reality? The real reliable distance is within 20m, and usually the network cable within 10m is the best signal quality. The maximum transmission distance and the maximum non-attenuating signal (not absolute) distance are two yards, and you have to rely on your own testing to know.

The maximum transmission distance of a single section is 100 meters. The transmission frequency of the Category 6 line is 1MHz 250MHz, and the comprehensive attenuation crosstalk ratio of the Category 6 cabling system should have a large margin at 200MHz, which provides twice the bandwidth of the Category 55.

The transmission performance of Category 6 cabling is much higher than that of Category 5e standards, and it is most suitable for applications with transmission rates higher than 1Gbps.

An important difference between Category 6 and Category 5 is that:

Improved performance in terms of crosstalk and return loss, which is critical for the next generation of full-duplex, high-speed network applications.

The basic link model is cancelled in the six types of standards, and the cabling standard adopts a star-shaped topology, and the required wiring distance is: the length of the permanent link cannot exceed 90m, and the channel length cannot exceed 100m.

The above content refers to Encyclopedia - Category 6 network cables.

In the Category 6 twisted pair cabling standard, the required cabling distance is as follows: the length of the permanent link cannot exceed 90m, and the channel length cannot exceed 100m. It seems that the transmission distance is not much higher than that of the Cat5 line, but it is much more stable.

If a shielded Category 6 wire is used, the performance and distance will be increased. I have used a normal Category 6 line and there are no problems within 150 meters. If it is within 200-300 meters, there will be a delay of 3-5 seconds, but it can be used normally.

If it's farther away, it's better to add a network repeater.

According to the regulations on cabling in the standard ANSI TIA EIA, regardless of the types of network cables, the maximum transmission distance is 100 meters, and the transmission distance exceeding the standard affects the speed and the quality is the same thing, and the quality depends on the speed.

The farthest effective transmission.

The distance of the loss is 100 meters.

Please note that the transmission distance here refers to the maximum rate, such as 100m, and if the rate is reduced to 10m, the transmission distance can usually be extended to 150-200m (depending on the quality of the network cable). Therefore, the transmission distance of PoE power supply is not determined by PoE technology, but by the type and quality of network cables.

Although in actual construction, the network cable with better quality can break through the limit of 100 meters and the equipment can work normally, but this practice is not worth recommending. This is because some potential problems do not manifest themselves immediately, but rather slowly over time, which can lead to follow-up maintenance problems.

As long as it is 4 pairs of twisted pairs, regardless of the type, the maximum transmission distance is set at 100 meters by the industry standard. Therefore, the cables produced by manufacturers are also produced according to this standard.

It does not mean that the network cable can only transmit to 100 meters, if it exceeds 100 meters, it can also be used as a voice signal line or control signal line.

If you need an ultra-long-distance transmission network cable, you can customize it to the manufacturer, which has no technical barriers, but there is no standard for such cables, and there is no standard for products, which may be easy to use, or may not be easy to use, in other words: things outside the standard are not necessarily very stable.

Regarding this issue, the super six categories (called 6A or enhanced six categories are more appropriate), the transmission rate is 10Gbps (10000Mbps), which is the legendary 10 megabits, and the theoretical transfer speed can reach 1280MB S, that is, the file can be transferred in 1 second.

The six categories of transmission rates are 1Gbps (1000Mbps), the legendary Gigabit, and the theoretical transfer speed is 128Mb s.

The transmission rate of Category 5e is 100Mbps, the legendary 100 megabits, and the theoretical transmission speed.

Note that the unit of rate and velocity: bps and b s are not the same. b=bit, b=byte.

Some people say that it is not right: Category 7 is 10Gbps 10 Gigabit rate, which is also right. This difference in understanding is due to the fact that the two sides are talking about different standard systems: the CLASSF under the TIA EIA system and the CLASSF under the ISO system.

The transmission frequency of Category 6 network cable is 1MHz 250MHz.

Good luck.
